OK, next suggestion is that you open the Lenovo Power Controls (it is a control panel), and see what Power Plan you have selected.
I normally use the one called "Power Source Optimized". I suggest you pick that one, then switch to advanced mode (there is a button for this purpose in the upper right corner of the Power Controls screen), and press the 'Reset to Defaults' button. Then reboot the machine and see how it performs.
Later on, you can go back into the Advanced mode and do some minor fine tuning. For example, I have noticed that by default, this power plan switches the wireless LAN to 'Maximum Power Savings' when on AC power - that doesn't seem right to me, so, I usually change that to 'Maximum Performance'.

I'm at a loss. and I've googled my little heart out. Any help would be appreciated.

Welcome to the forums - and thanks for a great initial post, all the needed information seems to be here.
Specifically, the following error from wpa_supplicant will most likely be best to dig into:
wlp3s0: failed to initialize driver interface
I see several results of this error in a google search, but none of them quickly translated into solutions yet. To get some more information on it, could you run the same wpa_supplicant command, but with the verbose debugging flag "-dd" and post the ouput here?
I don't have a intel wireless card, so I don't know what the diagnostic signs are for the problem addressed in the wiki, but you may want to try the modprobe options shown in this section of the wiki.
EDIT: there is a similar but unresolved thread on these forums here which points to using the -D flag for wpa_supplicant to specify other drivers. I was thinking this too upon my first reading, but I don't fully understand what these are so I was reluctant to suggest it. It certainly can't hurt anything to use the command in the wiki to see which drivers are available, then try each one.
EDIT 2: and this thread seems to indicate that the -D flag driver specification is the right solution. So start here with the -D flag and only if that fails follow up with my initial debugging suggestions.

ThinkPad W520: Parts Wrongly Listed in and/or Missing from Lenovo Order Status Page

I ordered a configured ThinkPad W520 off Lenovo.com for USD1500 yesterday. Later when I went back to check my order status, to my surprise some parts were either shown up incorrectly or simply missing.
For example my ThinkPad W520 includes (but not limited to) these parts:
Parts missing from Lenovo Order Status page:
UltraNav with TrackPoint & touchpad
Express Card Slot & 4 in 1 Card Reader
Question: Where are they? Why missing?
Parts shown incorrectly on Lenovo Order Status page:
I've ordered: 15.6" FHD (1920 x 1080) LED Backlit Anti-Glare Display, Mobile Broadband Ready
Lenovo Order Status page shows: SBB 15.6FHD (1900 X 1080) LED
Question: Why 1900 instead of 1920? What gives?
To be on the safe, I tried hard to match each of the parts consisting my ThinkPad W520. So far the above are my concerns. I know many of you are long-time Lenovo patrons. I'd appreciate your patience look through the below complete lists and advise if Lenovo indeed have received my order correctly.

Thinkpad W520 with Minidock+ Series 3 - Dual monitors and USB fail sporadically

Hello there,
I wonder if anyone has experienced problems ThinkPad W520 and Mini Dock Plus Series 3 (Part number: 433830U)? I run into problems with dual monitor and USB devices.
For dual monitor setup, sometimes only a single monitor is detected, sometimes no monitors are available in the NVidia control panel. Rigorous display detection doesn't help. Disabling Optimus in BIOS doesn't seem to affect it. After I dock and undock couple of times, reboot, unplug the power cord, it seems to resolve and both monitors work fine.
Also, I run into troubles with USB devices (keyboard/mouse). Sometimes they are not detected at all, but if I plug them into different USB ports on the mini dock, they are detected and work fine.
For me this problem happens about 50% of the time when I dock... Any ideas, insights or suggestions are greatly appreciated. Could it be a faulty Thinkpad, docking station or may be both? I really to upgrade next time to W530, but I've been through so many problems with W520, so I don't know if it's a good idea...
Thanks so much.
Solved!
Go to Solution.

If system update isn't finding anything, and the system works just fine on its own, it could potentially be a faulty Dock.
It could be overloaded. Could you try testing the dock using just one monitor, and no keyboard or mouse, to see if you run into the same issue. It would still be a faulty dock, but it may be a potential workaround for the time being.

Thinkpad w520 technical problems and warranty problems

I have a huge problem with my Lenovo ThinkPad W520 (Machine#4270CTO, SN * 11/07) purchased on US website in August 2011. Here is the story below:
In late December 2011 my laptop hardrive stopped working and as I am in Georgia(Caucasus) I went to the Lenovo Authorised Warranty Service Provider (not naming the company). They made the harddrive replacement very quickly and i was happy back then.
By start of January 2012 another problem came - my keyboard stopped completely working and as before I went to the service provider again and the faulty part was also changed in 2 weeks time.
By the end of January several problems occurred all together:
1. The speakers stopped working completely they just give an itching sound.
2. The track pad 2 buttons are completely unresponsive (not working) and the same 2 buttons on the keyboard - when I turn the trackpad off completely the keyboard buttons work.
3. 2 days ago computer completely went off and it is not starting at all. Power button lights on (green) than a flash turns on and immediately off and nothing happens besides the power button light .
I contacted Authorized Warranty Service Provider again some days ago but unfortunately they give me the following answer: They have a limit for service from Lenovo 1 times per computer which means they can order only 1 part replacement a month and as last keyboard replacement they made was on 12th of February 2012 I have to wait.
I'm really confused of the Lenovo quality and service ATM paid over 2,000 USD in a machine that had no sound and track pad for the last 2-3 weeks and now the computer is completely off and I can not even use it.
I used to be a Lenovo/IBM customer for quite a long time not only for my personal use but also for business and I never had problem with Lenovo products before or support. 'm Honestly tired of this computer and situation in general and instead of changing every item(Listed above) and wait 3 months till my Laptop is fully working is just nonsense and also to be an owner of a high priced brick with almost all parts changed under a guarantee is also not pleasant . I'm sort of stuck on what to do and I ask some solution for me is there any way to change the computer to new/refurbished or get my money back?
Moderator edit by bananaman: Masked serial number to prevent misuse.

I have had similar problems, and would recommend the following:
You probably wont get a resolution from the forums, only sympathy (which can help!).
Keep calling anyone you can find to do with Lenovo warranty about the issue utill you get a decent response. I was calling every day for 2 months. The process was so painful, I now live with the non-critical problems rather than deal with them.
Next time consider Dell. Their 3ry warranties have been outstanding - shipping parts to me anywhere in Eurpe within 48 hours, or collecting from my office and returning fixed 2 hours later, even in Gibraltar.

Upgrading Thinkpad W520 CPU and RAID is it possible.

Hello, I have Thinkpad W520. I'm interested two things. First is CPU upgrade. Which is highest CPU for this model? And Can I upgrade to 3rd generation CPU? As I see Ivy Bridge CPU use same socket. Second is RAID. I havent RAID option on my laptop. Is it possible to add this option?And last question I have warranty. Is it possible throught warranty upgrade CPU and setup RAID? Of course not for free.
Solved!
Go to Solution.

AFAIK, you can only upgrade within the Sandy Bridge generation. RAID is integral to the motherboard (you'd have to replace the motherboard with one that has RAID).
I don't think warranty does upgrades.

No RAID option in Thinkpad W520 BIOS

There is no RAID option in my Thinkpad W520 BIOS
I only get the "ACHI" and "Compatibility" mode.
I intended to put two SSDs in RAID 0 and did not want to buy 2 mechanical HDDs.
It appears that you only get the "RAID" controller when you order the W520 with 2 mechanical HDDs and let Lenovo configure the RAID for you .
I may have to send my unit back. I am VERY disappointed that this was not made clear at the Point of Sale.

I think the language has been changed. It now says; Internal RAID: not enabled or Internal RAID: configured by Lenovo.
When I ordered it said something more like Internal RAID: user configured or Internal RAID: preconfigured by Lenovo.
I do forget the exact wording, but the old wording pretty clearly indicated you had it but it was just not yet configured.
My actual order however says: Internal RAID not configured.

Thinkpad W520 Win7 Bluetooth device not recognized by Windows 7

Hello all,
Just received my Thinkpad W520 4270 CTO with bluetooth installed. It was a DOS workstation that I installed Win 7 x64 Ultimate on and I finally got all the drivers installed but the bluetooth software says there is no BT device connected to my laptop. I checked the BIOS settings and confirmed the BT is enabled. I even disabled it, saved, then enabled it to toggle. Hitting the Fn+5 combo doesn't trigger the light or any "Found New Hardware." When the laptop first boots up the BT light flashes along with the wifi light and the HDD activity light. I haven't yet been able to load another OS, but I'm downloading Arch Linux and BackTrack 5 to test to see it's possibly an OS issue.
Any thoughts or ideas would be helpful, it appears my Google-Fu has failed me as well.
EDIT: I realize the sticky about the "do not update the bluetooth drivers" but I'm not getting my bluetooth to work at all, not even being recognized by the OS as an "unknown device."
Solved!
Go to Solution.

I figured it out. It's laughably easy. Download the keyboard hotkey drivers and install them. It'll allow you to use the Functions at the top of your keyboard, then after you restart, hit Fn+F5 and you'll get a menu to enable Bluetooth on the OS, then Win7 should detect and install the drivers for it, or you can download the ones from Lenovo's site.

ThinkPad W520 Docking Station

Hey, everyone. My ThinkPad W520 should be arriving here tomorrow, and along with it, I ordered the ThinkPad Mini Dock Plus Series 3 - 170W. Currently, I have two monitors, one running at a resolution of 2048x1152, and the other one running at 1680x1050. I'm just now seeing that the limitation for the DVI ports is 1920x1080, so I'm guessing that won't work to hook these up.
My other route that I can go is by buying a DVI to DisplayPort cable, and then hooking them up that way. Lenovo's site claims that the dock has "Two DisplayPorts supporting 2560 x 1600 resolution," but would that mean I can hook up (these) two displays simultaneously? Inside the W520, is the NVIDIA Quadro 2000M Graphics with 2GB DDR3 Memory.
Thanks in advanced!
-Joe

well the real limitation of the single link dvi port is actually the 2048x1152 @ 60 hz, but this resolution monitor is seldomly used so they just use WUXGA or FHD as the stated maximum, 30 inch or 27 inch high resolution LCD uses dual link dvi (which is not supported by the dock dvi).
You can hock up two displayport monitors up and still run the internal LCD, since the new W520 uses the optimus graphics technology.

Why is it that the new macbook pro processor upgrade option only offers up to 2.8 Ghz with Intel Dual Core i7, when back in Sep 12 I bought a 2.9 Ghz Intel Dual Core i7 Macbook, is the new one tuned to go much faster anyway?

Why is it that the new Macbook Pro processor upgrade option only offers up to 2.8 Ghz boosting to 3.3 Ghz with Intel Dual Core i7, when back in Sep 12 I bought a 2.9 Ghz boosting to 3.6 Ghz Intel Dual Core i7 Macbook, is the new one tuned somehow to go much faster anyway, or will the new one be slower in fact? Or does the solid state drive compensate for the lack of increased processor capacity?

The CPU's come from different Intel 'families'. The older ones are 'Ivy Bridge' and the newer ones are 'Haswell'. Numbers alone will not determine the efficiency of CPU.

[CLOSED] Thinkpad W520 graphics issue

I'm trying to install X on my thinkpad W520 and I can't get it to work. I've tried the nouveau and nvidia drivers (with all the necessary reboots) and nvidia-beta from the AUR with no success. When trying to start X, I get an error that says no screen and it fails.
Vesa almost work. I get a screen, but the screen is shifted up so I can't see the top and there is a black bar along the bottom.
The graphics card is a NVIDIA Quadro 1000M Graphics. Any ideas?
Last edited by elcron (2011-07-11 02:43:55)

The Optimus switching technology on the Nvidia card doesn't work in Linux, so you have to choose your graphics at BIOS level. I went with the Intel discrete graphics to save battery, and it works okay for my needs. Of course, it depends on what your needs are.
I believe that the default is Intel graphics anyway, so configure X for that if you just want it going as soon as possible.

Disk partition for Thinkpad W520

I bought a machine of thinkpad w520. I want to partition my disk for three. How to do this? also it can not affect the rescovery disk. thank you for your advice.

Create recovery media first, so you can restore if anything goes wrong.
I'd say shrinking C: and creating some more logical partitions should work.

Showing Sub-Totals only for Specific Column in PowerView

Hi,
Is there a way of showing the sub-totals only for specific columns in a PowerView Matrix?
I am only aware of showing the sub-totals for all or non of the columns.
Thanks and Regards,
Justin

Hi Justin,
According to your description, you want to get sub-totals specific columns within columns group. Right?
In this scenario, we can use IIF() function in expression to achieve your goal. The expression will only return the total value when the column value is a specific value, otherwise we can make it return nothing. Try the following expression:
IIF(Fields!Column.Value="[specific value]",Sum(Fields!Total.Value),nothing)
We have tested this scenario in our local environment. Here are screenshots for your reference:

If you have any question, please feel free to ask.

MSataDetection on Thinkpad W520

I am running AVG virus software on my Thinkpad W520. I keep getting a notification that "mSataDetection" is trying to open an internet connection. I have no idea how to identify this application or whether or not it is safe. Is it a part of the Thinkpad software? Should the connection be allowed? I have done searches for the application and found a lot of questions with answers I don't understand. Any guidance would be appreciated. Thanks!
Solved!

'afternoon...
welcome to the community.
i get one interesting hit on google for "msatadetection": http://systemexplorer.net/file-database/file/msatadetection-exe
if it's accurate, then it's part of the Lenovo Message Center package, which does make network connections, and shouldn't be nefarious. whether it's worth allowing, and what it does with the info it gathers or sends, i can't answer as i routinely uninstall from my machines with an OEM image installed.
regards.

Winxp 64bit with ThinkPad W520

Dear All,
for last time we purchased ThinkPad W520 , we receive it with Win 7 64bit , but we want work with Winxp 64 bit,
Anway, I'm tried to install Winxp 64 bit and to install driver , But no any driver work fine else the Network Ethernal adapater.
I don't know what is the problem i made update for Winodws .
When i try to install for eample the video card ,it's start extracting the files, then when the last windows apear that say finish ,i checked the box to start install video card, but it's dispare and nothing happend.
And for sure i change this option in BIOS , Disable the optumus from BIOS, and make it discrete graphics.
Same for USB3.0 not work also...
I hope there is way to fix drivers in Winxp 64 bit.
Thank u.

While I never tried Winxp64 bit on my W520, I have tried using it before. It has a lot of driver issues like that because it was a very rare products so most 64bit drivers where desined for vista and up(Same with a lot of 64bit programs). Some will work but most have installer checks that have to be tricked into thinking that you are on a vista or higher machine. Most won't however do to the major changes that happened in vista and windows 7. That combined with the fact that I found Xp 64bit very unstable just on its on made me move away from it. Personally I feel that the changes Microsoft made in Windows 7 (both under the hood and UI) have major benifits and see very little reason to try to stick with xp.
Is there a reason that you need XP?
